In internet forums, the strategy of using multiple accounts to support oneself or attack others is called "participatory deception" or "spamming." Here are some common strategies: 1. **IFICATE attacks**: Creating multiple accounts to create an aura of false agreement or support to reinforce one's own argument or opinion. 2. **Split identities**: Using multiple accounts to split one's opinions or opinions to make them appear to be coming from different people. 3. **Fake reviews**: Creating accounts to post positive reviews about oneself or a product to increase one's credibility or reputation. 4. **Whitewashing**: Using multiple accounts to downplay or clarify one's negative reviews or criticisms. 5. **Split personality**: Creating multiple accounts to create a divisive or opposing ideology to anger or confuse others. 6. **False dissent**: Using accounts to post seemingly reasonable or open-minded criticisms or dissent to create a false sense of legitimacy or accountability. 7. **Brainwashing propaganda**: Posting repetitive, false, or misleading information, using multiple accounts to create a sense of urgency or importance. 8. **Bot Comments**: Using automated accounts to post repetitive or scripted comments or messages to create a false sense of consensus or support. 9. **Social Engineering**: Creating accounts to build trust or credibility, then using those accounts to manipulate or influence others. 10. **Account Farming**: Creating accounts to accrue reputation or credibility, then selling or using those accounts to promote products or services. 11. **Meta-Spam**: Using accounts to post comments or messages that criticize or ridicule other users’ comments or messages to create a sense of absurdity or confusion. 12. **Interaction**: Creating accounts to interact with others, then moving those conversations on LINE or other platforms to create a false sense of legitimacy or influence. 13. **Creating Fake Communities**: Using accounts to create seemingly legitimate or dedicated communities to promote products or services. 14. **Moderation**: Using accounts to format or isolate comments or messages to create a specific narrative or argument. 15. **Amplification**: Creating accounts to amplify or amplify specific information or ideas to create greater impact or attention.
